What is the rate of incidence for estrogen deficient vulvovaginitis?

Women most commonly experience symptoms of estrogen deficient vulvovaginitis after menopause. However, because estrogen levels can drop for many reasons, symptoms can also appear in women who are breastfeeding or getting treated for cancer, as well as women who have had ovarian surgery or a hysterectomy (removal of the uterus). Symptoms of estrogen deficient vulvovaginitis are common in postmenopausal women, though they are not a guaranteed to happen. Frequent sexual activity can help prevent symptoms associated with estrogen deficient vulvovaginitis.
